Genes affected

CS (HGNC:2422): (citrate synthase) The protein encoded by this gene is a Krebs tricarboxylic acid cycle enzyme that catalyzes the synthesis of citrate from oxaloacetate and acetyl coenzyme A. The enzyme is found in nearly all cells capable of oxidative metablism. This protein is nuclear encoded and transported into the mitochondrial matrix, where the mature form is found.

Ambry Genetics

Nov 11, 2024

The c.553T>C (p.Y185H) alteration is located in exon 6 (coding exon 6) of the CS gene. This alteration results from a T to C substitution at nucleotide position 553, causing the tyrosine (Y) at amino acid position 185 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
